For now linebackers are all lumped together, without regard to 3-4 or 4-3 scheme. For that matter, tackles and ends are lumped together as well. In the future I'd like to differentiate positions by scheme.

I also plan to add some more stats. For example, "victories" (or some other lame name) would be the number of plays that a defender made that resulted in a loss of expected points (EP) for the offense. They could be stuffs, passes defended, turnovers, sacks, or even tackles 6-yards deep on 3rd and 7. I've left success rate (SR) in the tables, but for defenders I think the total number of successes makes more sense.

The tables are sortable, with the default sort key set to +WPA. I think +WPA may be the most interesting stat, but +EPA is going to be a better indicator of long-term player ability.

Brian,I seem to remember taht when you first came out with Tackle Factor, K Dansby has a TF of 1.01, now he is shown as 1.24.Have you reworked this number?

What I am wondering is how we can use all these numbers together, to get a picure of the player.For now, I use these numbers as a guide, to see who is supposed to be good and not so good aand watch their performance to see if it matches.

I find it amazing how big of a lead Charles Woodson has above other CB's in the +EPA. It's nice to see from year to year and have all of this information available. It will be interesting once you have time to get the team pages updated to do analysis on different teams.

Re: K Dansby--There are a couple changes. First, I've removed all special teams tackles from both sides of the ledger: player tackles and team total tackles. Also, all ILBs and OLBs are lumped together, which doesn't make much difference.

Stats by team will be available very soon. Individual career stats are almost ready to go except for the guys who changed numbers. (Defenders love to change numbers for some reason.)

Instead of "victories," maybe I should just use "successes." That's a little clearer, and it's consistent with my Success Rate (SR) stat for offensive players.

Wouldn't the number of successes have to be somehow grounded by the number of opportunities for success? I realize this may be a bridge too far, it just seems like it's hard to judge Darrelle Revis by all the times he didn't have an opportunity to make a pick because he was covering a receiver so well that the guy didn't even get a look.
